获取页面所有参数

using System.Collections.Specialized; 

LogHelper.GetInstance().WriteMessage("==============================================================================start");
            NameValueCollection nvc = Request.Form;
            NameValueCollection nvc1 = Request.Params;
            //Params可以获取这三个集合的参数，不过一般不这么用，这个集合比较大，性能不好。所有我们平时都用具体的，要么Form，要么QueryString
            //获取 System.Web.HttpRequest.QueryString、
            //System.Web.HttpRequest.Form、
            //System.Web.HttpRequest.ServerVariables

            if (keys == null || keys.Length <= 0)

                LogHelper.GetInstance().WriteMessage("Request.Form参数Length为0");
            }

                string key = k;
                string value = Request.Form[k];
               
                LogHelper.GetInstance().WriteMessage(string.Format("Request From key:{0},{2},Value:{1}{2}",key,value,Environment.NewLine));//加个换行符
